New Post: System.TypeInitializationException: The type initializer for '' threw an exception

I would like to convert pdf to png. It is working on my developer computer, but when i deploy to the server, i always get an exception. I'm using x64 version and ghost script 9.06. The VC Redist 2012 x64 is also installed.

The exception is:

System.TypeInitializationException: The type initializer for '<Module>' threw an exception. ---> <CrtImplementationDetails>.ModuleLoadException: The C++ module failed to load while attempting to initialize the default appdomain.
---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: Invalid token for impersonation - it cannot be duplicated.
